Macrophages play a central role in lung physiology and pathology. Herein, we show in mice that alveolar macrophages (AMs), unlike other macrophage types [interstitial macrophages (IMs), and peritoneal and splenic macrophages], constitutively express PD-L1, thereby possessing a superior phagocytic ability and the capacity to repress cytotoxic T lymphocytes (CTLs) by cis- and trans-interacting with CD80 and PD-1, respectively. This extraordinary ability of AMs assures optimal protective immunity and tolerance within the lung. These findings uncover a unique characteristic of AMs and an innate immune function of PD-L1 and CD80, therefore help understand lung physiology, diseases and PD-L1/PD-1-based immunotherapy.
